ipfs-js v0.0.11

ipfs.js

Wrapper for node-ipfs-api

Browser friendly

Run npm install ipfs-js

Or reference dist/ipfs.min.js inside a <script /> to expose the global ipfs

Example

1) Set IPFS CORS access

   ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["*"]'
   ipfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT", "GET", "POST"]'
   ipfs config --json API.HTTPHeaders.Access-Control-Allow-Credentials '["true"]'

2) Start IPFS

   ipfs daemon

3) Upload example directory

git clone https://github.com/ConsenSys/ipfs.js && cd ipfs.js

For non-default ipfs configurations, you can run ./example.url to ipfs add -r example and print the local gateway's url

4) Open IPFS gateway

Navigate to the url echoed from ./example.url in the browser, or run ./example.url | xargs open to open it on OSX

Methods

ipfs.setProvider({host: 'localhost', port: '5001'})

• localhost and 5001 are the defaults when calling without arguments
• is also equivalent to ipfs.setProvider({host: '/ip4/127.0.0.1/tcp/5001'})

ipfs.setProvider(require('ipfs-api')('localhost', '5001'))
